How many sub portals (parent and child) that DNN can handle? Or how many portals maximum for fair performance within single DNN host?
Please anybody who could share information. Thanks

we run over 100 sub portals on a single portal.  Set up in virtual environment.  Lots of ram and lots of processor power, lots of drives, lots of backups.

There are disadvantages to doing so much on a single portal.   Your Heart about stops if when you see errors in the database.   Keeping the database rows and columns in perfect shape can be painful.   Full event logs happen over time.   Every module install causes the system to reset for everyone.

The advantages are licenses for modules sometimes allow cheaper solution for a single portal, unlimited subs.   Much easier to keep track of 1 database than 100 databases when doing upgrades.

We are considering opening up a 2nd main portal which may get 100s under it as well.  In set ups where there is only a core group of people with host access and 100s of admins.. multi-subportals are a nice way to go.   But if you have a lot of people spread out with host access.   Give them all their own portal.

That sounds reasonable.   You will have some customizing to do with the template system to create user group and give only admin access to pages and not the full portal.  Otherwise several 3rd party providers have modules that auto portal create and help with billing.  Dnn can be set up in a farm and of course your hardware needs will be a factor.

Sounds like you got some work ahead of you. :)
